Kodiak supplies 1-2 pieces of Fiber Flow with each unit purchased. Fiber Flow is a packing/cushioning material that is very porous allowing for adequate airflow inside the cargo area. The payload liner in the cargo area is ribbed to allow for this airflow.
Any packing/cushioning material that does not restrict this airflow will work. *Note - filling the excess payload area with any small-fill material such as foam peanuts will restrict the airflow and reduce the performance capabilities of the container. More.
